That is not normal. The leakage isn't enough. You can adjust the VCV:

1. Engine off.

2. Loosen the two bolts of the VCV, just loosen, so that the VCV can be moved.

3. Put linkage in full load and keep it there

4. Rotate the VCV until you feel resistance.

5. Tighten the VCV in that position.

It could be that the VCV is dirty inside. Unfortunately the VCV cannot be opened easily, but you can use a spray can of brake cleaner to clean it. Remove the VCV and douse the VCV through the openings with brake cleaner. Let the VCV dry before installing. Be careful with brake fluid, it is very flammable.

Check if the green dashpot really is a dashpot and not a valve.

If you don't feel resistance (step #4), the VCV does need adjustment or replacement. Both not very easy. I don't know if adjustment is possible (as it is with the VCV of the MW pump), but the VCV had to be drilled open. Replacement is not easy, as they are not very popular in the States.
